The full system,live in five minutes.
Pick a number, pay, install the eSIM — and the whole business phone system is on. Auto-attendant playing, working hours active, voicemail capturing with transcripts going to email, recording armed if you turn it on. Mechanics are identical to a travel eSIM (direct push on iPhone, QR on Android), but the line is permanent and the number is yours.

One-tap eSIM install.
Apple introduced CTCellularPlanProvisioning with iOS 12 in 2018. It lets a carrier push an eSIM activation prompt directly to your iPhone — you tap "Continue", iOS downloads the profile, and the line is active. No camera, no QR scanning, no Settings menu navigation.
- Works on iPhone XS, XR, 11, 12, 13, 14, 15, 16 (and SE 2nd/3rd gen)
- iPhone 14 and newer are eSIM-only — no physical SIM tray

- Apple Watch (Series 3+ cellular) inherits as a paired line

Common questions
From completing checkout to making the first call, typically five minutes. The eSIM installation itself takes 30-60 seconds; the rest is choosing a number, paying, and confirming the eSIM activation prompt on your phone.
iPhone XS and newer support Apple's CTCellularPlanProvisioning — Kelir sends an installation prompt directly to your phone via Apple's servers, and you tap to install. No camera or QR involved. Android phones, older iPhones, and some non-Apple devices use a QR code shown in the Kelir app, which you scan to install the eSIM profile.
No. Kelir installs as a second line on your phone, alongside your personal SIM (whether that's a physical SIM or another eSIM). Modern phones support multiple active eSIM profiles — iPhone XS+ supports two active simultaneously, with up to 8 stored.
Any phone with eSIM support and at least one free eSIM slot.

Kelir's interconnect partner is Telnyx, which delivers cellular service via wholesale agreements with major US carriers. From the user perspective: your number rings as a real US cellular line with VoLTE HD voice, regardless of which carrier handles the underlying interconnect.
Yes. eSIM transfer between your devices is supported on Solo and Team plans. From the Kelir app, generate a new activation profile for the new device — old eSIM deactivates, new eSIM activates, no number reset.
